Importance of meteorological variables for aeroplankton dispersal in an urban environment
2016
Passive wind dispersal is one of the major mechanisms through which organisms disperse and colonize new areas. The detailed comprehension of which factors affect this process may help to preserve its efficiency for years to come. This is especially important in the current context of climate change, which may seriously alter weather regimes that drive dispersal, and is crucial in urban contexts, where biodiversity is dramatically threatened by pollution and fragmentation of natural patches. Despite its interest, the analysis of factors affecting aeroplankton dispersal in urban environments is rare in literature. We sampled aeroplankton community uninterruptedly every 4 hours from 17th May t…
Human milk and mucosal lacto- and galacto-N-biose synthesis by transgalactosylation and their prebiotic potential in Lactobacillus species.
2017
Lacto-N-biose (LNB) and galacto-N-biose (GNB) are major building blocks of free oligosaccharides and glycan moieties of glyco-complexes present in human milk and gastrointestinal mucosa. We have previously characterized the phospho-β-galactosidase GnbG from Lactobacillus casei BL23 that is involved in the metabolism of LNB and GNB. GnbG has been used here in transglycosylation reactions, and it showed the production of LNB and GNB with N-acetylglucosamine and N-acetylgalactosamine as acceptors, respectively. The reaction kinetics demonstrated that GnbG can convert 69 ± 4 and 71 ± 1 % of o-nitrophenyl-β-d-galactopyranoside into LNB and GNB, respectively. Those reactions were performed in a s…
H89 Treatment Reduces Intestinal Inflammation and Candida albicans Overgrowth in Mice
2020
Deregulation of the dynamic crosstalk between the gut microbiota, intestinal epithelial cells, and immune cells is critically involved in the development of inflammatory bowel disease and the overgrowth of opportunistic pathogens, including the human opportunistic fungus Candida albicans. In the present study, we assessed the effect of N-[2-(p-bromocinnamylamino)ethyl]-5-isoquinolinesulfonamide (H89), a protein kinase A inhibitor, on the migration of macrophages to C. albicans through dextran sulphate sodium (DSS)-challenged Caco-2 cells. We also investigated the impact of H89 on intestinal inflammation and C. albicans clearance from the gut, and determined the diversity of the gut microbio…
Probiotic Potential of Leuconostoc pseudomesenteroides and Lactobacillus Strains Isolated From Yaks
2018
The purpose of this study was to evaluate the antibacterial activity and safety of bacterias with probiotic potential isolated from free-ranging Tibetan yaks in high altitude regions of Tibet. For this purpose, one Leuconostoc pseudomesenteroides strain (named P1) and two Lactobacillus johnsonii and Lactobacillus mucosae strains (named LY1 and LY2), respectively, were isolated from fecal samples of Tibetan yaks. The antibacterial activity of the isolates was studied using Escherichia coli (E. coli ATCC 25922), Staphylococcus aureus (S. aureus ATCC 26112), and Salmonella enteritidis (S. enteritidis NCTC 13349) as indicator pathogens. The results showed that LY1 had high antibacterial efficac…
European Guidelines (S1) on the use of high‐dose intravenous immunoglobulin in dermatology
2016
Background The treatment of severe dermatological autoimmune diseases and toxic epidermal necrolysis (TEN) with high-dose intravenous immunoglobulin (IVIg) is a well-established procedure in dermatology. As treatment with IVIg is usually considered for rare clinical entities or severe clinical cases, the use of immunoglobulin is not generally based on data from randomized controlled trials that are usually required for the practice of evidence-based medicine. Owing to the rarity of the indications for the use of IVIg, it is also unlikely that such studies will be available in the foreseeable future. Because the high costs of IVIg treatment also limit its first-line use, the first clinical g…
Using the Johnson-Neyman Procedure to Detect Item Bias in Personality Tests
2016
I present an alternative to a widely used item-bias analysis procedure known as the ANOVA method. The new method is based on the Johnson-Neyman procedure, which is a multiple regression-based technique with properties that can overcome the major weaknesses of the ANOVA method. I introduce the proposed procedure in a non-technical manner, provide an illustrative example, and suggest guidelines for empirical analysis that can be readily applied in personality research.
María Magdalena. Continuidad y variación en la cultura audiovisual (1897-2014)
2017
El objetivo principal de esta tesis consiste en analizar la presencia de María Magdalena en las producciones audiovisuales del periodo comprendido entre 1897 y 2014. Dichas producciones proceden de Europa, Estados Unidos, Canadá y México. El marco metodológico general a partir del que se plantea el análisis es la iconología, entendida como Zwichenraum o tierra de confluencias. En concreto, la noción de continuidad y variación, iniciada por Aby Warburg y continuada por Fritz Saxl, es la principal cuestión teórica en la que se basa la aproximación. El estudio se lleva a cabo en perspectiva diacrónica con el objetivo de detectar dichas fases de continuidad y variación del personaje a lo largo …

Elīzijas lietošanas variācijas analīze Borisa Džonsona un Žistēna Trido runās
2022
Veidojot saistītu runu, jāņem vērā, ka bieži vien vairāk tiek uzsvērts konkrētās runas konteksts, nevis pareizas gramatikas un izrunas īpatnības. Šādās runās var novērot daudzas saistītās runas īpatnības atkarībā no runātāja emocionalitātes, attieksmes pret konkrētās runas ideju, valodas variācijām, runas tempa, intonācijas utt. Šajā pētījumā galvenā uzmanība pievērsta runas iezīmei elīzija, kas rodas, ja saistītās runas veidošanas laikā tiek izlaista kāda skaņa. Šī pētījuma mērķis ir izpētīt saistītās runas pazīmes - elīzijas īpatnības, vēsturiskos un mūsdienu aspektus un analizēt šīs pazīmes sastopamības variācijas Lielbritānijas un Kanādas premjerministru runās, ņemot vērā runas formalit…
